Methods

bindStream(String name) → Future<Stream<Object?>>
Binds a JavaScript {emit, close, error} sink to a Dart stream.
call(String method, List<Object?> args, {Duration? timeout}) → Future<Object?>
Calls a function stored on this context's globalThis.
callPluginExport(JsPlugin plugin, String method, List<Object?> args, {Duration? timeout}) → Future<Object?>
Calls one export declared by the supplied plugin.
override
callRaw(String method, List<Object?> args, {Duration? timeout}) → Future<String>
Calls a global function and returns the raw QuickJS bridge string.
dispose() → Future<void>
释放 Context 及其回调、插件和模块状态；重复调用返回同一 Future。
disposePlugin(JsPlugin plugin, {Duration? timeout}) → Future<Object?>
Calls the plugin's optional disposal export.
override
eval(String code, {Duration? timeout, String name = '<eval>', Map<String, Object?> tempGlobals = const {}}) → Future<Object?>
同步求值 code 并将结构化结果转换为 Dart 值。
evalRaw(String code, {Duration? timeout, String name = '<eval>', Map<String, Object?> tempGlobals = const {}}) → Future<String>
同步求值 code 并返回底层 Bridge 的原始字符串。
initPlugin(JsPlugin plugin, {Map<String, Object?> context = const <String, Object?>{}, Duration? timeout}) → Future<Object?>
Calls the plugin's optional initialization export.
override
injectFunction(String name, FutureOr<Object?> callback(List<Object?> args)) → Future<void>
Temporarily injects a Promise-returning Dart function into this context. Reusing name replaces and releases the previous callback. The function remains available until the context is disposed.
injectStream<T>(String name, Stream<T> stream) → Future<void>
Injects a Dart stream as a JavaScript async iterable in this context. It remains available until the context is disposed.
loadFeatures(JsFeatures features, {JsFeaturesConflictPolicy conflictPolicy = JsFeaturesConflictPolicy.reject}) → Future<void>
Installs a capability bundle directly into this context.
loadPlugin(JsPlugin plugin, {bool initialize = true, Map<String, Object?> context = const <String, Object?>{}, Duration? timeout}) → Future<void>
Features, validates and optionally initializes a dynamic plugin in place.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
pumpTimers() → Future<Duration?>
Advances this context's JavaScript event loop once.
run(String code, {Duration? timeout, String name = '<run>', Map<String, Object?> tempGlobals = const {}}) → Future<Object?>
求值 code、等待其 Promise 结果并转换为 Dart 值。
runModule(String source, {required String name, Map<String, String> modules = const {}, Duration? timeout}) → Future<String>
以 name 为入口模块执行 source，并提供额外 modules。
runRaw(String code, {Duration? timeout, String name = '<run>', Map<String, Object?> tempGlobals = const {}}) → Future<String>
求值 code、等待 Promise 并返回底层 Bridge 的原始字符串。
toString() → String
A string representation of this object.
inherited
validatePlugin(JsPlugin plugin, {Duration? timeout}) → Future<void>
Validates the plugin manifest, module graph, and declared exports.
override

Operators

operator ==(Object other) → bool
The equality operator.
